WATER-CLOSET VENT.

Specification oi' Letters Patent.

Patented April 6, 1909.

Application filed September 23, 1907. Serial No. 39,107.

To all whom it may concern:

Be it known that l, HARRY i). lALLAoE, a citizen of the I lnited States, and a resident ol' hlinneapolis, county ol:l Hennepin, and

State of Minnesota, have invented certain new and useful Improvements in ""atcr- Closet Vents, oilI which the Vfollowing is a specification.

The obj ect ol indT invention is to provide a hood Vl'or the upper end ol' a closet vent pipe, capable ol attachment to any pitch ol' rool' and adapted to receive a temporary plug, by means ol' which the pipe may be sealed during the operation ol' testing the system.

further object is to provide device which will positively prevent the entrance of sewer gas into the house from the vent pipe, and a l'urther object is to dispense with all lead and solder joints, usually employed with devices ol this kind.

ri'he invention consists generally in the various constructions and coinbin ations hereinaiter described and set 'lorth in the claires. In the accompanying drawings, Y forming part o'lI this speciipication, Figure l is a seotional view illustrating the application oi' my invention to a roo'l. Fig. 2 is a detail view partially in section showing the device detached 'lrom the roof. Fig. 3 is a side elevation ol' the device and Fig. Llis a top view. ln the drawings, 2 represents a roof board having an opening 3 through which the closet vent pipe 4E passes.

5 is a hood, preferably ol' sheet metal, having llano'es 6 'for securing it to the rooli' boards *b and provided with an opening 7 over which a hood section 8 pivoted at 9 on the side walls ol' the hood proper is arranged. v This hood section is provided with a pipe l() extending upwardly therefrom and adapted to register with the opening .7 in the hood and is capable oi' adjustment with the hood section baci: and forth over the opening 7 to allow it to receive the upper end of the pipe 4l and adapt the device l'or roo'ls ol' diilerent pitch. :in internally threaded ring l] is provided in the upper end of the pipe IO and a casting l2 is eX- teriorly threaded and 'litted within said ring and has a threaded lower end i3 to receive the threaded upper end oi'I the vent pipe 4. An opening i4 is formed in the casting 12 to register with the pipe 4l. rhis construction allows the mounting oi' the hood around the upper end ol the vent pipe and its connection with the said pipe without the necessity of making lead joints and iitting the parts together and sealing them, as usually required in work ol' this kind.

The casting is interior-ly threaded at its upper end and to test the system it is only neces sary to insert a threaded plug into the end el the casting, when the vent pipe will be sealed and the system may be tested with air pressure.

in l? ig. 2, I have shown a inofii'lied construction, wnich consists in providing a hood section having a telescoping upper end I6 that is capable oi' moving up and down to accomniod ate itself to the length ol' the vent pipe and the upper end ol' the pipe instead ol' being threaded, is secured to the casting 17 by the lead joint 18. In other respects, the device corresponds to the hood and casting shown in Fig. I.

T his device is composed of but iew parts and capable ol'l convenient application to a vent pipe, and will enable the plumber to dispense with all lead and solder joints and. at the saine time will positively prevent the entrance oil sewer gas from the open end ol' the vent pipe into the house.

l claim as my invention:

l. The combination with a pipe projecting therethrougl'i, of sleeve inclosing said vent pipe and spaced therei'rorn, a casting Iitting within the upper end of said sleeve and l'iaving a socket to receive the upper end of said vent pipe, and said casting having an opening therethrough registering with the opening in said vent pipe, and a test plug 'litting within the opening in said casting and temporarily sealing the upper end of said vent pipe.

2. The combination with a roof and a vent pipe projecting therethrough, oi a sleeve inclosing the upper end of said vent pipe and spaced therefrom, an interiorly threaded ring provided within said sleeve, an ext -riorly threaded casting 'fitting within said ring and having an opening therethrough and a socket to receive the upper end of said. vent pipe, and a test plug litting within the opening in said casting, and temporarily sealing the upper end of said vent pipe for the purpose specified.

3. T he combination with a rooic and a vent pipe projecting therethrough, of a hood having a section inclosing said vent pipe and spaced therefrom, a sleeve also inclosing said vent pipe and having a telescopic conrool and vent neetioii with said hood section, and a test plug .adapted to be mounted in the upper end oi" said sleeve and verticallT adjustable therewith to adapt the device to vent pipes ol' different height, substantially as described.

4f. The combination with a vent pipe, of a sleeve inolosing the saine, a cap for the open end ol' said sleeve having e lieiiiietir-,ally sealed joint with said vent pipe and a test plug removably mounted on said eep and ten'iporarily closingl the open end of said vent pipe.

The combination with a iool' and a vent pipe projecting' therethrough, of a sleeve inclosiiig said vent pipe and havingl an adjustable connection With seid roof, and a test plug;- adapted to be carried l-y said Sleeve and normally close the open end oi said vent pipe and vertieall5T adjustable therewith to adept the device to vent pipes ol" diilerent height.

6. The combination, with roof end a vent pipe, of a jaolet, a sleeve mounted on said jacket and inelosing said pipe and eX- tending to the top thereof and spaced therefrom to prevent formation of frost on seid pipe, and a cap closing1 the space between said pipe and sleeve and having a removable test plug above the open end of said pipe.

'7. The Combination, With a roof and a vent pipe pifoiecting therethrough, of e jacket, a sleeve mounted on said j aelet and arranged to oscilla-te thereon to adept it to roofs ol" diflerent pitch, seid sleeve inolosing the upper portion of said pipe and spaced from the Walls thereof to prevent formation o frost on said pipe, and a test plug Carried by said cap and pipe and temporarily closing` the top of said pipe, substantially es described. y

S. The combination, with aroof end a vent pipe, of a sleeve inclosingl the upper exposed end of said pipe and spaced irornfthe Walls thereof, and a cap closing the space hetweei'i said pipe and sleeve and having` a removable test plugg above the open end of said pipe, substantially es described.

ln Witness whereof, T, have hereunto set niv hand this 14th day of Sept-einher, 1.907.
